There is nothing like IMing the correct amount of ketamine. It might take one or two tries to find the right dose, ( I’m 210 lbs, and I use about 110mg in 1.5ml H2O.
I originally used pharma vials, but they aren’t around anymore ( for me anyways).
Micron filter is definitely the way to go, if u want to live a healthy life. I have used a piece of cotton off a a-tip lately, bc I trusted the source, and I’m so depressed, I take immune suppressants anyway. But bad shit happens. So don’t be like me, unless you are ok with walking into the hospital and telling the doctor exactly what you did, if it starts to feel warm, or raises, or u get a fever, or anything happens that is out of the norm. But iv happens too fast for my taste. IM is the way K was meant to be used , and u probably won’t want to use any other way. There is a fine line, and if u dose too high, u just will wake up an hr later. There is a dosage chart on the web somewhere. Mg/kg body weight. I forget the math tho. look around and you’ll find it. It u can wait till u get a vial or micron filter. ( u can order micron filters off amazon btw) that’s the move. I have had success with dissolving the k in h2o, then IMing into my thigh. Like if I am sitting on the edge of the bed and look down. I see my thighs. Look at the right thigh, find the center, move towards the outer edge A half inch, insert needle. Make sure no blood flows back. Then slowly insert. If it’s painful, you are doing it wrong, or ur k is fucked. At least buy from a reputable source, not some guy outside the bar, ya know.
